Bao (Chi Bao) and Van (Ha Kieu Anh) have been married for a long time without a child, but Bao’s mother always longs for a grandchild. The test result concludes that Van is infertile. Van asks her staff – Mai (Kim Thu) to have a baby with Bao by a 50-million-dong contract. Mai agrees because she needs money to treat her mom’s disease. It is difficult for Bao to accept this contract due to his love for his wife. After giving birth, Mai can’t give the child to anyone, so she runs away with it and Quang (Cao Minh Dat)- her lover. They meet Bao and Van in a life-threatening situation for the baby.
